The inline filtration characteristics of freshly blended and degraded AMK fuels at low temperature are examined in this report. A basic needle valve degrader was modified to include partial recirculation of degraded fuel and heat addition in the bypass loop. At fuel temperatures below -20C, degradation becomes increasingly difficult and a single pass technique results in unacceptable filtration performance. Recirculation of a fraction of the degraded fuel and heat addition in the bypass loop improved low temperature degradation performance. In addition, this report addresses the problems associated with blending the AMK additive with Jet A at various base fuel temperatures. These tests established that AMK blended at temperatures between 0 and +30C produced adequate fire protection characteristics within 15-20 minutes after blending.
